Multifunctional systems for the sponge city

Urban structure in transition

More function. More future.

Our cities are facing profound changes. Heavy rainfall, heat waves and advancing climate change are challenging us to rethink existing structures. Sealed surfaces that do not absorb water and store heat are exacerbating the problems - with consequences for the environment and quality of life.

We are convinced that the cities of tomorrow must become more resilient, greener and more liveable. This can only be achieved if we reduce sealing and at the same time create spaces in which people can move, meet and feel comfortable.

Our answer to this is surfaces that can do more: innovative, multifunctional and sustainable. With our paving systems, we design surfaces that not only support, but also improve the microclimate, retain water and set architectural accents - without sealing the ground.

In this way, we combine functionality and climate protection to create a vision that starts today and lasts tomorrow: More climate. More future.

Rethinkingunsealing

Today's urban areas need to be able to do more: pave surfaces with a high load-bearing capacity , allow rainwater to seep away, improve the microclimate and promote biodiversity.

The best solution: GDM.KLIMASTEIN aBG. It is effective over large areas, highly water-permeable (ψm 0), regenerable and achieves an evaporation performance like a meadow - even where greening is not possible. In this way, it brings the "meadow" principle back to every urban area.

Green - blue - gray in combination: vegetation pavers specifically supplement climatic stone surfaces with lively, green zones. Together, they create a climate-active surface that manages rainwater, reduces heat and makes the city a better place to live.

The perfect combination for climate-active urban spaces

The GDM. KLIMASTEIN is the basis for resilient, durable and climate-active surfaces - fully water-permeable and with an evaporation capacity like a meadow.

Vegetation paving stones are used where additional greenery is possible: they bring insects, herbs and visual relief to the surface, promote the microclimate and increase the quality of the area.

The green-blue-grey result: more biodiversity and a lively appearance, effective rainwater management and retention and resilient, functional surfaces with maximum water permeability.

Together, they form the building blocks of the sponge city: a multifunctional surface system that absorbs heavy rainfall, reduces heat and makes urban spaces fit for the future.

Our contribution to the sponge city principle

The climate stone - proactive for a better urban climate

The GDM. KLIMASTEIN is not just a water-permeable stone. It is a technology carrier that makes climate impact measurable.

Vegetation pavers - a natural addition with added design value

Not every surface can or should be greened. However, where it is possible, our vegetation p avers bring more biodiversity and a looser look to the area - without sacrificing functionality.

Small joint, big effect!

Eco paving

An inner-city square paved partly with vegetated grass liner joint blocks and partly with climate blocks in line with the sponge city principle. On the left is a house wall covered with climbing plants and on the right a modern building with an anthracite-colored façade.

The highlight

Climate blocks and vegetation pavers interlock functionally and creatively and together form an urban surface that is efficient and lively.

1. rainwater management

  • Storage, evaporation & infiltration directly on the surface
  • Relief of the sewer system
  • Support of the sponge city principle

2. quality of stay & climate effect

  • Heat reduction through evaporation & reflection
  • Air purification through catalyst function
  • Improvement of the urban climate

3. ecology & biodiversity

  • Plantable joints promote biodiversity
  • Habitats on previously dead areas
  • Combination of function and nature

4. design & flexibility

  • Combination of paved & green areas
  • Individual formats, colors, laying methods
  • Visual enhancement & greening of urban spaces

5. economy & technology

  • Resilient, durable, low-maintenance
  • Allowable retention areas
  • Suitable for new planning & renovation

"Climate protection starts on the ground: climate resilience as a strategy for the future"

A city is only climate resilient when the natural water cycle is active again - when the city has become a sponge city. This white paper shows which solutions are already working today.

GDM.KLIMASTEIN - Water-sensitive urban planning

Our contribution to the sponge city principle: climate protection is more important for our future than anything else - we are preparing the ground for it. With the climate block as a paving stone, sealed surfaces are given climate-friendly properties that previously seemed unthinkable.
